Involved In

This protein is involved in 22 target(s):

Target	Category	Definition
G1/S transition of mitotic cell cycle	biological process	The mitotic cell cycle transition by which a cell in G1 commits to S phase. The process begins with the build up of G1 cyclin-dependent kinase (G1 CDK), resulting in the activation of transcription of G1 cyclins. The process ends with the positive feedback of the G1 cyclins on the G1 CDK which commits the cell to S phase, in which DNA replication is initiated. [GOC:mtg_cell_cycle]
in utero embryonic development	biological process	The process whose specific outcome is the progression of the embryo in the uterus over time, from formation of the zygote in the oviduct, to birth. An example of this process is found in Mus musculus. [GOC:go_curators, GOC:mtg_sensu]
DNA repair	biological process	The process of restoring DNA after damage. Genomes are subject to damage by chemical and physical agents in the environment (e.g. UV and ionizing radiations, chemical mutagens, fungal and bacterial toxins, etc.) and by free radicals or alkylating agents endogenously generated in metabolism. DNA is also damaged because of errors during its replication. A variety of different DNA repair pathways have been reported that include direct reversal, base excision repair, nucleotide excision repair, photoreactivation, bypass, double-strand break repair pathway, and mismatch repair pathway. [PMID:11563486]
DNA damage response	biological process	Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating damage to its DNA from environmental insults or errors during metabolism. [GOC:go_curators]
spermatogenesis	biological process	The developmental process by which male germ line stem cells self renew or give rise to successive cell types resulting in the development of a spermatozoa. [GOC:jid, ISBN:9780878933846, PMID:28073824, PMID:30990821]
cell population proliferation	biological process	The multiplication or reproduction of cells, resulting in the expansion of a cell population. [GOC:mah, GOC:mb]
positive regulation of cell population proliferation	biological process	Any process that activates or increases the rate or extent of cell proliferation. [GOC:go_curators]
protein ubiquitination	biological process	The process in which one or more ubiquitin groups are added to a protein. [GOC:ai]
hemopoiesis	biological process	The process whose specific outcome is the progression of the myeloid and lymphoid derived organ/tissue systems of the blood and other parts of the body over time, from formation to the mature structure. The site of hemopoiesis is variable during development, but occurs primarily in bone marrow or kidney in many adult vertebrates. [GOC:dgh, ISBN:0198506732]
negative regulation of granulocyte differentiation	biological process	Any process that stops, prevents, or reduces the frequency, rate or extent of granulocyte differentiation. [GOC:mah]
cellular response to UV	biological process	Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an ultraviolet radiation (UV light) stimulus. Ultraviolet radiation is electromagnetic radiation with a wavelength in the range of 10 to 380 nanometers. [GOC:mah]
somatic stem cell population maintenance	biological process	Any process by which an organism retains a population of somatic stem cells, undifferentiated cells in the embryo or adult which can undergo unlimited division and give rise to cell types of the body other than those of the germ-line. [GOC:bf, ISBN:0582227089]
T cell activation	biological process	The change in morphology and behavior of a mature or immature T cell resulting from exposure to a mitogen, cytokine, chemokine, cellular ligand, or an antigen for which it is specific. [GOC:mgi_curators, ISBN:0781735149]

rhythmic process	biological process	Any process pertinent to the generation and maintenance of rhythms in the physiology of an organism. [GOC:jid]
intrinsic apoptotic signaling pathway	biological process	The series of molecular signals in which an intracellular signal is conveyed to trigger the apoptotic death of a cell. The pathway starts with reception of an intracellular signal (e.g. DNA damage, endoplasmic reticulum stress, oxidative stress etc.), and ends when the execution phase of apoptosis is triggered. The intrinsic apoptotic signaling pathway is crucially regulated by permeabilization of the mitochondrial outer membrane (MOMP). [GOC:mtg_apoptosis, GOC:yaf, PMID:11919192, PMID:17340152, PMID:18852119]
ubiquitin-dependent protein catabolic process via the C-end degron rule pathway	biological process	The chemical reactions and pathways resulting in the breakdown of a protein or peptide covalently tagged with ubiquitin, via the DesCEND (destruction via C-end degron) pathway. In the DesCEND pathway, C-terminal residues (C-end degrons) in substrates are recognized by Cul2-RING and Cul4-RING E3 ligases, whereupon the substrates are linked to ubiquitin and then delivered to the proteasome for degradation. C-end degrons can be present in full-length proteins, truncated proteins or proteolytically cleaved forms. [PMID:29775578, PMID:29779948]
